Rom Harré and Fathali M. Moghaddam have designed a textbook and brought together additional voices that speak to the similarities and differences of two seemingly separate domains in psychology. This bridge-building seeks to encourage a new generation of undergraduate students studying psychology to more fully appreciate the real potential for the study of human behavior, and as such it will represent a more provocative alternative to standard general psychology textbooks. It also be used in a host of courses, namely on the conceptual and philosophical nature of psychology, social psychology, critical psychology and cognitive science.
